INSTRUCTIONS FOR USE

Install the batteries

In shortThe machine takes up to six 6-volt batteries, laid out as in Fig. 1, and Advance or a qualified electrician should install them. Always take off the negative (ground) cable first and put it back on last to prevent sparks.‌‌​⁠‌⁠​‌⁠‍‌‌‍‍⁠‌​‍‌‌​​​​​​‍‍​​​‌​‍‍​‌​‍‌​​⁠‍​⁠⁠​‍⁠⁠⁠⁠​‍‍‌​‍​
WARNING! Use extreme caution when working with batteries. Sulfuric acid in batteries can cause severe injury if allowed to contact the skin or eyes. Explosive hydrogen gas is vented from the batteries through openings in the battery caps. This gas can be ignited by any electrical arc, spark or flame. Do not install any lead-acid battery in a sealed container or enclosure. Hydrogen gas from overcharging must be allowed to escape.

When Servicing Batteries...‌‌​⁠‌⁠​‌⁠‍‌‌‍‍⁠‌​‍‌‌​​​​​​‍‍​​​‌​‍‍​‌​‍‌​​⁠‍​⁠⁠​‍⁠⁠⁠⁠​‍‍‌​‍​

  • Remove all jewelry
  • Do not smoke
  • Wear safety glasses, rubber gloves and a rubber apron
  • Work in a well-ventilated area
  • Do not allow tools to touch more than one battery terminal at a time
  • ALWAYS disconnect the negative (ground) cable first when replacing batteries to prevent sparks.
  • ALWAYS connect the negative cable last when installing batteries.
CAUTION! Electrical components in this machine can be severely damaged if the batteries are not installed and connected properly. Batteries should be installed by Advance or by a qualified electrician.
  1. Remove the batteries from their shipping crate and carefully inspect them for cracks or other damage. If damage is evident, contact the carrier that delivered them or the battery manufacturer to file a damage claim.
  2. Turn the Master Key Switch (A) OFF and remove the key.
  3. Remove the recovery tank from the machine. NOTE: Disconnect the tether and the vacuum motor wiring and lift the tank straight up and off the machine.
  4. Your machine comes from the factory with enough battery cables to install six 6 volt batteries. Using at least (2) people and an appropriate lifting strap, carefully lift the batteries into the battery compartment and arrange them exactly as shown in FIGURE 1. Secure the batteries as close to the front of the machine as possible. If installing a mono-block battery use an overhead hoist.
  5. Install the battery cables as shown. Position the cables so the battery caps can be easily removed for battery service.
  6. Carefully tighten the nut in each battery terminal until the terminal will not turn. Do not over-tighten the terminals, or they will be very difficult to remove for future service.
  7. Coat the terminals with spray-on battery terminal coating (available at most auto parts stores).
  8. Put one of the black rubber boots over each of the terminals and connect the Battery Pack Connector (20).

Detergent system preparation and use (EcoFlex models only)

In shortEcoFlex machines only. The detergent cartridge holds up to 2.2 gal (8.32 L), and the system should be purged whenever you change detergents. To purge, hold the Solution and Detergent switches for 3 seconds; the purge then runs 10 seconds.‌‌​⁠‌⁠​‌⁠‍‌‌‍‍⁠‌​‍‌‌​​​​​​⁠⁠​​​‌​‍‍​‌‌‍​‍​‌‌‌‍‍‍‍⁠⁠‍‍​⁠‌‌​‍​

The Detergent Cartridge (29) is located behind the Side Access Panel (27). Fill the detergent cartridge with a maximum of 2.2 gal (8.32 L) of detergent.‌‌​⁠‌⁠​‌⁠‍‌‌‍‍⁠‌​‍‌‌​​​​​​⁠⁠​​​‌​‍‍​‌‌‍​‍​‌‌‌‍‍‍‍⁠⁠‍‍​⁠‌‌​‍​

SERVICE NOTE: Remove the detergent cartridge from the detergent box prior to filling to avoid spilling detergent on the machine.

It is recommended that a separate cartridge be used for each detergent you plan to use. The detergent cartridges have a white decal on them so you can write the detergent name on each cartridge to avoid mixing them up. The system should be purged of previous detergent when switching to a different detergent. When installing a new cartridge, remove the Cap (AA) and place the cartridge in the detergent box. Install the Dry Break Cap (BB) and detergent hose as shown.

The system should be purged of previous detergent when switching to a different detergent. SERVICE NOTE: Move machine over floor drain before purging because a small amount of detergent will be dispensed in the process.

To purge when changing detergents (scrub and solution systems must be off)

  1. Disconnect and remove the detergent cartridge.
  2. Turn the Key Switch (A) ON. Press and hold the Solution Switch (F) and the Detergent Switch (J) down for 3 seconds. Release the switches when the detergent purge icon (K10) appears on the display and the Detergent Switch Indicator (J1) starts flashing. NOTE: Once activated the purge process takes 10 seconds. See illustration on next page for Detergent System indicators. Normally one purge cycle is adequate to purge the system.

To purge weekly (scrub and solution systems must be off)

  1. Disconnect and remove the detergent cartridge. Install and connect a Cartridge filled with clean water.
  2. Turn the Key Switch (A) ON. Press and hold Solution Switch (F) and the Detergent Switch (J) down for 3 seconds. Release the switches when the detergent purge icon (K10) appears on the display and the Detergent Indicator (J1) starts flashing. NOTE: Once activated the purge process takes 10 seconds. See illustration on next page for Detergent System indicators. Normally one purge cycle is adequate to purge the system.

When the detergent level is nearing the bottom of the cartridge it is time to refill or replace the cartridge.

SERVICE NOTE: Follow the “To Purge Weekly” instructions above if the machine is going to be stored for an extended period of time or if you plan to discontinue use of the detergent system.

Detergent ratio (scrub system must be on)

No detergent is dispensed until the scrub and detergent systems are enabled and the Drive Pedal (8) pushed forward.

  • The detergent icon (K4) will always be displayed when the detergent system is on.

There are 4 modes of EcoFlex operation:

  1. Plain Water Cleaning Mode - During scrubbing, the detergent system can be turned off at any time by pressing the Detergent ON/OFF Switch (J) to allow scrubbing with water only. Detergent Indicator (J1) will be OFF.
  2. Minimum Concentration Detergent Mode – Burst of Power Indicator (G1) ON (Activated by momentarily pressing Burst of Power Switch (G) when in maximum concentration detergent mode). See below the steps “To program the Minimum Detergent Level”.
  3. Maximum Concentration Detergent Mode – Burst of Power Indicator (G1) OFF (Activated by pressing and holding Burst of Power Switch (G) for 2 seconds). See below the steps “To program the Maximum Detergent Level”. Do not use a concentration level exceeding the detergent manufacturer’s recommendation.
  4. Burst of Power Cleaning Mode – Press the Burst of Power Switch (G) to increase the detergent ratio for one minute to the pre-programmed “maximum concentration” detergent level (as noted in programming instructions below). This will also cause the solution flow rate to increase to the next level and the scrub pressure to increase to the next level. Burst of Power Indicator (G1) will blink for one minute.

To program the maximum concentration detergent level

  1. Press the OneTouch™ Scrub switch (D) to activate the scrub system.
  2. Press and hold the Burst of Power Switch (G) for approximately 2 seconds until the indicator (G1) is OFF (maximum concentration detergent mode).
  3. Press and hold the detergent switch for approximately 2 seconds until the indicator (J1) flashes.
  4. While the indicator is flashing, pressing and releasing the detergent switch will cycle through the available ratios (400:1, 300:1, 256:1, 200:1, 150:1, 128:1, 100:1, 64:1, 50:1, 32:1).
  5. Once the desired ratio is displayed on the screen (K9), stop and it will save the setting after 3 seconds.
  6. Whenever the maximum concentration detergent setting is set to a lower concentration than the current minimum programmed concentration setting, the minimum concentration default setting will be equal to the maximum concentration setting until changed by the operator.

To program the minimum concentration detergent level

  1. Press the OneTouch™ Scrub switch (D) to activate the scrub system.
  2. Ensure the Burst of Power Indicator (G1) is ON (minimum concentration detergent mode).
  3. Press and hold the detergent switch for approximately 2 seconds until the indicator (J1) flashes.
  4. While the indicator is flashing, pressing and releasing the detergent switch will cycle through the available ratios (Note: only ratios that are a lower concentration or equal to the maximum detergent setting will be available.
  5. Once the desired ratio is displayed on the screen (K9), stop and it will save the setting after 3 seconds.

Once set, the detergent flow rate automatically increases and decreases with the solution flow rate, but the detergent ratio remains the same.

INSTRUCTIONS FOR USE

Operating the machine

WARNING! Be sure you understand the operator controls and their functions. While on ramps or inclines, avoid sudden stops when loaded. Avoid abrupt sharp turns. Use low speed down hills.
In short Turn the key on, release the parking brake, hold the Solution Switch (F) for 5 seconds to pre-wet the floor, then press the Scrub ON Switch (D) and drive forward. When the recovery tank is full the float shuts everything off except the drive, so empty the tank; when the Battery LOW Indicator (K8) comes on, take the machine to be recharged.‌‌​⁠‌⁠​‌⁠‍‌‌‍‍⁠‌​‍‌‌​​​​​‌​‌​​​‌​‍‍​‍⁠‍​‌​⁠​⁠‍‌‍‍⁠‍⁠‍‌​‍‌​⁠‍

To scrub...

Follow the instructions in “preparing the machine for use” section of this manual.‌‌​⁠‌⁠​‌⁠‍‌‌‍‍⁠‌​‍‌‌​​​​​‌​‌​​​‌​‍‍​‍⁠‍​‌​⁠​⁠‍‌‍‍⁠‍⁠‍‌​‍‌​⁠‍

  1. See Figure 8. While seated on the machine, adjust the seat and steering wheel to a comfortable operating position using the adjustment controls (23) and (5).
  2. Turn the Master Key Switch (A) ON (I). This will display the control panel indicator lights. Reference the Battery Condition Indicator (K5) and Hour Meter (K3) before proceeding.
  3. Release the Parking Brake (6). To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal (8) to go forward or the rear of the pedal for reverse. Vary the pressure on the foot pedal to obtain the desired speed.
  4. Press the Solution Switch (F) and hold for 5 seconds to pre-wet the floor. NOTE: This will help prevent scarring of the floor surface when starting to scrub with dry brushes. This must be done prior to pressing the Scrub ON Switch (D).
  5. Press the Scrub ON Switch (D) once for Regular Scrub, twice for Heavy Scrub or three times for Extreme Scrub mode. Both the solution flow and detergent (EcoFlex models) flow have 3 presets that coincide with the 3 scrub modes (see Control Panel).

    NOTE: There is a solution flow rate override function if you wish to increase solution flow without increasing scrub pressure. Hold the Solution Switch (F) for 3 seconds (solution indicator will start flashing) and then let go. You then have 3 seconds to set a different flow rate by simply pressing the Solution Switch (F) repeatedly until the Solution Flow Indicator (K1) shows the rate you desire (1-5 / see Control Panel). Any subsequent scrub pressure adjustments will reset the solution flow rate to default.

  6. When the Scrub ON Switch (D) is selected, the brushes, squeegee and side brooms (cylindrical models) are automatically lowered to the floor. The scrub, solution, vacuum, detergent (EcoFlex models) and side brooms (cylindrical models) systems are all automatically enabled and will start when the Drive Pedal (8) is activated. Any individual system can be turned OFF or back ON by simply pressing its switch at any time during scrubbing.

    NOTE: When operating the machine in reverse the squeegee automatically raises.

  7. Begin scrubbing by driving the machine forward in a straight line at a normal walking speed and overlap each path by 2-3 inches (50-75 mm). Adjust the machine speed and solution flow when necessary according to the condition of the floor.

    NOTE: The maximum scrub speed can be increased by pressing the Scrub Speed Switch (L). The default maximum scrub speed is less than the maximum transport speed. Pressing this switch overrides this default and allows scrubbing at the maximum transport speed.

    If scrubbing on a smooth floor surface or double-scrubbing turning on the Traction Control™ button (B) regulates the drive wheel torque providing increased control and enhanced traction on the floor.

    The side broom height can be adjusted. See the “Side Broom Maintenance” section of this manual.

CAUTION! To avoid damaging the floor, keep the machine moving while the brushes are turning.
  1. When scrubbing, check behind the machine occasionally to see that all of the waste water is being picked up. If there is water trailing the machine, you may be dispensing too much solution, the recovery tank may be full, or the squeegee tool may require adjustment.
  2. The machine defaults to the last cleaning mode used Minimum or Maximum Concentration Detergent (if detergent is installed and was activated). Press the Burst of Power Switch (G) to override the current cleaning mode and temporarily increase scrub pressure, solution flow and the detergent ratio (unless in Maximum Concentration). This will cause the indicator to flash for one minute, solution flow rate will increase to the next level, scrub pressure will increase to the next level and the detergent ratio will be at the Maximum Concentration level (detergent system will be turned on if it was off).

    NOTE: Pressing and holding the Burst of Power Switch (G) for 2 seconds changes between the Minimum and Maximum Concentration operating modes. The EcoFlex system will only function if the scrub system (D) has been enabled.

  3. For extremely dirty floors, a one-pass scrubbing operation may not be satisfactory and a “double-scrub” operation may be required. This operation is the same as a one-pass scrubbing except on the first pass the squeegee is in the up position (press the Vacuum/Wand Switch (I) to raise the squeegee). This allows the cleaning solution to remain on the floor to work longer. The final pass is made over the same area, with the squeegee lowered to pick up the accumulated solution.
  4. The recovery tank has a shut-off float (15) that causes ALL systems to turn OFF except the drive system when the recovery tank is full. When this float is activated, the recovery tank must be emptied. The machine will not pick up water or scrub with the float activated.

    NOTE: All other indicators vanish and a “Recovery Tank FULL” Indicator (K7) appears on the Display Panel when the float is activated. If the control repeatedly gives a full indication when the tank is not full, the automatic shut-off feature can be disabled, have a qualified service technician refer to the service manual to perform this function.

  5. When the operator wants to stop scrubbing or the recovery tank is full, press the Scrub OFF Switch (E) once. This will automatically stop the scrub brushes and solution flow and the scrub deck will raise up. The squeegee will raise up after a brief delay and the vacuum will stop after a brief delay (this is to allow any remaining water to be picked up without turning the vacuum back on).
  6. Drive the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Drain Hose (19) from its rear storage area, then remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled flow of waste water). Refill the solution tank and continue scrubbing.

NOTE: Make sure the Recovery Tank Cover (1) and the Recovery Tank Drain Hose (19) cap are properly seated or the machine will not pick-up water correctly.

When the batteries require recharging the Battery LOW Indicator (K8) will come on, the scrub brushes and solution flow will stop and the scrub deck will raise up. The squeegee will raise up after a brief delay and the vacuum will stop after a brief delay. Transport the machine to a service area and recharge the batteries according to the instructions in the Battery section of this manual.

  2. Remove the Tension Straps (BB).
  3. Slip the rear blade off the alignment pins.
  4. The squeegee blade has 4 working edges as shown below. Turn the blade so a clean, undamaged edge faces toward the front of the machine. Replace the blade if all 4 edges are nicked, torn or worn to a large radius.
  5. Install the blade, following the steps in reverse order and adjust the squeegee tilt.

To Reverse or Replace the Front Squeegee Blade...

  1. Raise the squeegee tool off the floor, then loosen the (2) Thumb Nuts (CC) on top of the squeegee and remove the squeegee tool from the mount.
  2. Remove both rear Tension Straps first.
  3. Remove all the wing nuts that hold the front blade in place, then remove tension strap and blade.
  4. The squeegee blade has 4 working edges as shown below. Turn the blade so a clean, undamaged edge faces toward the front of the machine. Replace the blade if all 4 edges are nicked, torn or worn to a large radius.
  5. Install the blade, following the steps in reverse order and adjust the squeegee tilt.

Squeegee adjustment

There are two squeegee tool adjustments possible, angle and height.

Adjust the squeegee angle whenever a blade is reversed or replaced, or if the squeegee is not wiping the floor dry.

  1. Park the machine on a flat, even surface.
  2. Lower the squeegee, move the machine ahead slightly and adjust the squeegee tilt and height using the Squeegee Tilt Adjust Knob (22) and Squeegee Height Adjust Knobs (28) so that the rear squeegee blade touches the floor evenly across its entire width and is bent over slightly as shown in the squeegee cross section.
  3. Squeegee height is pre-set at the factory but may require periodic adjustment due to caster wear. Proper squeegee height is achieved when the front squeegee blade is in contact with the floor but not bent over. Use Height Adjust Knobs (28) to ensure blade position is uniform left to right.
  4. The Tilt Adjust Knob (22) is used to adjust the tool angle for uniform contact from center to tips of blade.

Side skirt maintenance

In short The side skirts channel waste water to the squeegee. If a little water leaks out under them, lower the blades with the Adjuster Collars (FF); when the main blade is worn on one edge, turn it to a clean edge, and replace the blades as a set when all 4 edges are worn.‌‌​⁠‌⁠​‌⁠‍‌‌‍‍⁠‌​‍‌‌​​​​​‌‌⁠​​​‌​‍‍​​‍​‌‌​‍‌⁠⁠⁠⁠​⁠​‌‌‌⁠⁠‌​‌‌

The side skirt’s function is to channel the waste water to the squeegee, helping contain the water within the machines cleaning path. During normal use the blades will wear in time. The operator will notice a small amount of water leaking out underneath the side skirts. A height adjustment can easily be made to lower the blades so that all the water can be pick-up by the squeegee.‌‌​⁠‌⁠​‌⁠‍‌‌‍‍⁠‌​‍‌‌​​​​​‌‌⁠​​​‌​‍‍​​‍​‌‌​‍‌⁠⁠⁠⁠​⁠​‌‌‌⁠⁠‌​‌‌

To reverse or replace the scrub system side skirt(s) ...

  1. See Figure 12. Loosen the (2) side skirt Retainer Knobs (AA) (2 per side) and remove the Skirt Assemblies (BB) from the scrub deck. NOTE: Remove the skirts by first sliding them forward and then pulling them off.
  2. Remove all the hardware that holds the blades to the skirt housings. NOTE: The main blade on each skirt housing is held on with Tool-less Retainers. Simply loosen the large Wing nuts (CC) and then turn the Knobs (DD) on the outside of the skirt housing until they are horizontal and push through the slots. The small inside Blade (EE) on disk models is held on by a plate and two screws and nuts, it has 2 working edges.
  3. The main skirt blade has 4 working edges as shown. Turn the blade so a clean, undamaged edge faces toward the center of the machine. Replace the blades as a set if all 4 edges are nicked, torn or worn beyond their ability to be adjusted.
  4. Reinstall the skirt housing assemblies onto the machine and adjust the blade for proper contact to the floor when the brush deck is placed in the scrub position.

Side skirt height adjustment

  1. The side skirt housing knob retainer screw studs have leveling Adjuster Collars (FF) that can be raised or lowered to compensate for blade wear.
  2. To adjust, remove the Skirt Assemblies (BB) from the scrub deck to access the Adjuster Collars (FF). Adjustment Tip: The skirts Retainer Knobs (AA) can be loosened with skirts left on and the Adjuster Collars (FF) rotated by reaching under the skirt housing.
  3. Turn the Adjuster Collars (FF) (Up or Down) to where the blades just fold over enough when scrubbing that all the waste water is contained inside the skirting. NOTE: Make small adjustments to obtain good blade wiping. Do not lower the blades too much to where they fold over excessively and cause unneeded blade wear.

Side broom maintenance

In short Set the side broom height in the Adjust Mode so the bristles contact the floor from the 10 O’clock to the 3 O’clock area (Fig. 13). Store the machine with the side brooms raised, and replace a side broom when the bristles are worn to 3 inches (7.62 cm) or it becomes ineffective.‌‌​⁠‌⁠​‌⁠‍‌‌‍‍⁠‌​‍‌‌​​​​​‌‍‌​​​‌​‍‍​⁠​​‌⁠​‌⁠‌‌‍‌‍‍‍‌‌‍‌‌‌‍‍⁠

The side broom(s) move dirt and debris away from walls or curbs and into the path of the main broom. Adjust the side broom so that the bristles are contacting the floor from the 10 O’clock (AA) to the 3 O’clock (BB) area shown in Figure 13 when the broom is down and running.‌‌​⁠‌⁠​‌⁠‍‌‌‍‍⁠‌​‍‌‌​​​​​‌‍‌​​​‌​‍‍​⁠​​‌⁠​‌⁠‌‌‍‌‍‍‍‌‌‍‌‌‌‍‍⁠

The side brooms are adjusted through the adjust mode. To enter the “Adjust Mode” perform the following steps...

  1. Turn the Key Switch (A) to the OFF position (O).
  2. Press and hold the Side Broom Switch (C) and the Scrub Off Switch (E).
  3. While holding the switches (C & E), turn the key switch to the ON position (I).
  4. Continue to hold the switches for 2 seconds until side broom, scrub off and scrub on LED’s turn on.
  5. Release the switches. The Display (K) will now show “SIDE BROOM ADJUSTMENT”.

Once inside of the “Adjust Mode” perform the following steps to adjust the side broom...

  1. Press Scrub On Switch (D) to lower the side brooms and press the Side Broom Switch (C) to raise the side brooms until the desired height is reached.
  2. To save the side broom height position, press the Scrub Off Switch (E). The side brooms will raise to the up position and the display will show a key icon (indicating that the key switch should be cycled off and on).
  3. The machine has now been reprogrammed to use the new side broom height position.

NOTE: The machine should be stored with the Side Brooms in the raised position. The Side Brooms should be replaced when the bristles are worn to a length of 3 inches (7.62 cm) or they become ineffective.

To replace the Side Broom...

  1. Raise the Side Broom(s).
  2. Remove the large Pin (CC) holding the side broom on and remove the broom.
  3. Install the new broom by sliding it UP onto the shaft and re-installing the Pin (CC).
